How would you handle missing values when calculating the mean in R?

  • Use the na.rm = TRUE parameter in the mean() function
  • Replace missing values with 0 before using the mean() function
  • Exclude missing values from the vector before using the mean() function
  • All of the above
When calculating the mean in R, you can handle missing values by using the na.rm = TRUE parameter in the mean() function. Setting na.rm = TRUE instructs R to ignore missing values and compute the mean based on the available non-missing values. This ensures that missing values do not impact the calculation.
